If you are assuming to do rename() somehow, it would not be true. And if
so, you might want to rethink about the patch. (btw, I'm not thinking
deeply yet though, I guess we have to limit unlink() too)

Well, anyway, I'd like to see stable/clean read-only support at first.
(with new nfs option, and with MS_RDONLY). After that, we can
enable write support.
